New Hampshire requires anyone paid to assess mold in a home to hold a valid national third-party mold assessment certification. Assessment means inspections, surveys, remediation plans or collecting mold samples. The state law does not set a license for the cleanup itself. Ask for the assessor's certification and who issued it. Check the Office of Professional Licensure and Certification's site for current requirements.
